This is the ultimate home made stimulator. I should go commercial with this idea, I am sure I could make millions...I have tried many things, but there is nothing that compares. Take a rubber can cooler, the kind that stores sell that you place your beer or soda can in to keep cool during the summer. Cut the side with scissors down to the bottom, then remove the round bottom. It will come out in one, round piece. Now open up the cooler and cut strips off the end until when closed it will fit around your engorged cock. Let it be a little loose. Now tape it together so that it forms a round cylinder. Use Duct Tape, it works best. Now place the top (or bottom) back on and tape in place. You will be advised to tear off several two inch strips of duct tape ahead of time to tape it all together. Now that you have it all together tear off longer strips of duct tape and wrap the entire cooler. all around the cylinder and across the top. You will notice a 3/8 inch hole in the top. Go to the hardware store and buy three feet of 3/8' clear flexible tubing. (Tygon Tubing)Insert the tubing into the hole but not far enough to extend into the sleeve, just about 1/2 inch is all. Now tape it in place. When you are done it will look like it is made with duct tape.
Now lubricate the sleeve with your favorite lubricant and slide your cock in. Take the end of the tubing and place it in your mouth and alternately blow and suck on it and feel the sleeve slide up and down your erection. It won't be long before you explode in the best climax you've ever had. The nifty thing about this is that you can drive while doing it and no one is the wiser. Especially if the tubing is brought up under your clothes and to your mouth.
You can also place the sleeve between pillows on the couch and fuck it. By placing the tip of your tongue in the tubing it will cause a suction on your cock on the back stroke that will drive you wild. But be careful, don't ejaculate too quickly, I like the pleasure to go on for at least an hour. My favorite is driving along quickly sucking and blowing while the sleeve dances up and down on my hard cock even in traffic. I can be alongside a great looking woman doing it. Sometimes we look at each other while I am exploding. You will be hooked on this technique, believe me. After you have tried it, please email me and let me know how you like it.
